I think I agree. At least the way our company does microservices and staffing, this makes sense. We have a team if about 6 devs owning about 12 apps, many of them microservices. The overhead for technical upgrades and prod support is high. They always want us working on new stuff too. If a product owning team is around long enough, eventually you have to stop adding new apps to that team unless you retire some of the old ones.
